Recessed Light Fixture With Lightguide Trim for Dual Lighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lighting fixtures require multiple units to provide different types of lighting, which can be costly and inefficient in terms of installation space.
Innovation Solution
A recessed light fixture design that incorporates a lightguide trim, featuring a first light source for illumination and a second light source for nightlight or alert lighting, with a reflector to direct light through a lens and a broad surface of the lightguide trim, allowing for dual functionality in a single fixture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple light fixtures are used to provide different lighting functions, then lighting versatility is improved, but installation cost and space requirements increase
Solution Approach 1:
The patent combines multiple light sources (first light source for illumination, second light source for night light) and multiple light guides (first light guide, second light guide) into a single integrated fixture housing. This merging of previously separate fixtures into one unified device achieves different lighting functions while reducing the total number of fixtures needed, thereby lowering installation cost and space requirements while maintaining lighting versatility
2Adaptability or versatility
If multiple light fixtures are installed to provide different lighting, then lighting versatility is improved, but installation space increases
Solution Approach 1:
The patent integrates multiple lighting functions into a single fixture that occupies one ceiling opening rather than requiring multiple separate fixtures. The housing contains both the first and second light sources along with their respective light guides, consolidating what would traditionally require multiple ceiling installations into a single space-efficient unit
3Adaptability or versatility
If multiple light fixtures are used to achieve different lighting purposes, then lighting versatility is improved, but overall cost increases
Solution Approach 1:
The patent consolidates multiple light sources, light guides, reflectors, and housing components into a single manufacturable unit. By designing the fixture as an integrated assembly containing both illumination and night light functions, the patent enables economies of scale in manufacturing and reduces the total cost compared to producing and installing multiple separate fixtures
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables efficient use of space and cost reduction by providing multiple lighting functions within a single fixture, including downlight and nightlight capabilities, while optimizing light distribution through the lightguide trim.
Implementation Method 1
a first light source that emits a first light
Implementation Method 2
a reflector positioned to reflect at least a portion of the first light
Implementation Method 3
a second light source that emits a second light
Implementation Method 4
a lightguide trim positioned around at least a portion of the reflector. The second light source is positioned to emit the second light toward a narrow edge of the lightguide trim
Data Source
AI summary
A recessed light fixture includes a first light source that emits a first light, a second light source that emits a second light and a reflector positioned to reflect at least a portion of the first light. The recessed light fixture further includes a lightguide trim positioned around at least a portion of the reflector. The second light source is positioned to emit the second light toward a narrow edge of the lightguide trim.
